Reversible molecular motion of a bis-calix[5]arene host driven by a photoresponsive guest

Article abstract of DOI:10.1002/asia.201100738

Control by light: Reversible switching between closed and open conformations of a calix[5]arene-based receptor was conveniently controlled, at the supramolecular level, exclusively through light inputs by exploiting the photoisomerization of a tailor-made azobenzene guest.
